Steels
RWL-34 is my favourite steel. It is a powder steel made in Sweden. It features a very fine grain structure. With the right heat treat it gets scary sharp and holds the sharpness for a long time. It is fairly easy to sharpen for the user which is something I value. It is somewhat comparable to ATS-34 in composition yet features added Vanadium. This gives it finer grain structure and adds to the edge holding. I use S30V on some of my models or if the customer requests it or if the size needed is not available in RWL-34.
For those dress up knives I like to use Damasteel. Damasteel is a stainless Damascus made from RWL-34 and PMC-27. The later is similar to 12C27.
Heat treat
All my RWL-34, ATS-34 and Damasteel blades gets a professional heat treat by Haustrup, Denmark. This is a company dealing only with heat treating. The blades get hardened in a vacuum furnace and are cryogenically stress relieved at -196 °C (-385 °F). The stress relieve gives 3 benefits:
- The wear resistance is greatly increased.
- The knife gets a keener edge.
- The strength is greatly increased.
The process is very expensive, but it gives you the best knife you could wish for.
Handle materials
G10 is an epoxy sealed, woven-glass composite reinforced with glass fiber. Its even stronger than Micarta and I just love it.
Carbon fibre is a material comparable with Micarta and G10. But the resin is reinforced with woven carbon fibre. Its extremely light.
Micarta is a phenolic resin reinforced with layers of paper or cloth. Its very strong and stable.
